What 19294 covers

During breast-conserving surgery, the surgeon prepares the excision cavity and positions an applicator so radiation can be delivered intraoperatively. The service is performed in the operating room after removal of the breast lesion; the applicator is placed in the resulting tumor bed for the planned intraoperative treatment. Radiation delivery itself is a distinct service, commonly performed by a radiation oncologist with the surgical team present.

Report 19294 as an add-on with the primary partial mastectomy procedure, not as a stand-alone service. The operative report should support the partial mastectomy, preparation of the cavity, and placement of the applicator for intraoperative radiation. CMS treats this as an add-on paid within the primary procedure’s global period. The code represents cavity preparation and applicator placement, not the radiation dose or delivery.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

19294 billing questions

Can 19294 be reported by itself?

No. It is an add-on code and must be billed with an eligible primary procedure, typically the partial mastectomy.

How does 19294 differ from 19301?

19301 reports the partial mastectomy. 19294 reports the additional work of preparing the tumor cavity and placing the applicator for intraoperative radiation.

Does 19294 include radiation delivery?

No. It covers cavity preparation and applicator placement; radiation delivery is a distinct service, such as the treatment represented by 77424 or 77425.

What documentation supports 19294?

The operative report should describe the partial mastectomy, preparation of the tumor bed, and placement of the applicator for intraoperative radiation.

How does the global-period rule affect reporting?

CMS pays this add-on within the primary procedure’s global period. It must be reported with the primary procedure rather than as a separate stand-alone service.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
